Beschreibung
Zusammenfassung:	The invention discloses a light-operated elastic fiber and a preparation method thereof.The preparation method comprises the steps that azobenzene-terminated polycaprolactone and derivatives of azobenzene-terminated polycaprolactone are synthesized to serve as guest molecules, then multi-arm pillararene is synthesized to serve as host molecules, and in a proper solvent, supramolecular gel of a cross-linked network is constructed through the host-guest interaction of polycaprolactone chain segments and pillararene. The azobenzene-terminated polycaprolactone and the derivatives of the azobenzene-terminated polycaprolactone are linear polycaprolactone (Azo-PCL-Azo), polycaprolactone-b-polyethylene glycol-b-polycaprolactone (Azo-PCL-b-PEG-b-PCL-Azo), star-shaped polycaprolactone (S (PCL-Azo) N, N = 3-6), and star-shaped polyethylene glycol-b-polycaprolactone (S (PEG-b-PCL-Azo) M, M = 4, 6 and 8). According to the light-operated elastic fiber and the preparation method thereof, superfine fiber can be pulled out fr
